These Dehydrated Pizza Flaxseed are one of my favorite crackers, the other being my Everything Bagel Flax Crackers. They are both delicious in their own way.
These raw crackers taste like pizza. They have a sweet concentrated tomato flavor combined with pizza spices.
Making your own crackers is super easy to do. They are a lot healthier than store-bought, with no processed ingredients.
Eat them with vegan cream cheese or your favorite dip. They are raw, vegan, low-carb, and gluten-free.

🧾 Ingredients

- Flaxseeds: Get gelatinous when liquid is added. I used golden flaxseeds, but either brown or golden flaxseeds work. You could also use chia seeds. If you use chia seeds, you'll use ½ as much.
- Spices: I used marjoram, thyme, oregano, basil, parsley, rosemary, sage, salt, and pepper. Combined they remind me of pizza flavors. You could also use Italian seasoning or your favorites.
- Tomatoes: Any tomatoes will work.
- Onion: Adds a pungent flavor.
- Water: Thins the tomato mixture to soak the flaxseeds in.
This is an overview of the ingredients. To see the full list of ingredients with measurements and instructions, see the recipe card at the bottom of this post.
📖 Variations / Additions
- Italian seasoning
- Onion powder

🔪 Instructions

Step 1: In a blender combine tomatoes, spices, and water. Blend until smooth.

Step 2: Place flaxseeds in a large bowl. Pour tomato mixture over flaxseeds and stir. Soak for at least an hour to get gelatinous.

Step 3: Pour the mixture onto a Teflon-lined dehydrator sheet or use a spoon and pour spoonfuls of the mixture to make round crackers. Dehydrate for 24-72 hours (depending upon how thick you make them and if they are individual crackers or a full sheet), or until crispy.
Flip halfway through for a faster dehydrating time. My crackers were pretty thick, so they took a long time to dehydrate.
You can score them with a butter knife, which makes the crackers easier to break apart and form squares. If you're going to score them, do it after they have been dehydrating for a while so that the knife forms lines and does not disappear.
👩🏻🍳 Recipe FAQs
I have never baked these raw crackers so I cannot tell you how they'll turn out. If you decide to try it, I would set your oven to the lowest temperature.

Ines says
Hi Willow,
These sound really tasty. Could sun-dried tomatoes be used instead of fresh for more tomato flavor? If so, do you have an idea of how much? I have sun-dried tomatoes dry or in oil.
Willow Moon says
Hi Ines, you could try it, but I don't know what the amounts would be. Instead of fresh tomatoes, you would need more water. For the sun-dried tomatoes I would use the dry sun-dried tomatoes (not in oil).
I'm going to throw out some numbers that may or may not be the right amounts. For my everything bagel flax crackers I used 3 cups water (total) to 2 cups of flaxseeds. So you would need 3 cups of water instead of the 1/2 cup water (to replace the liquid from the fresh tomatoes). For the sun-dried tomatoes I would start with 2 cups, but you might need as much as 4 cups. I would soak them in the water to plump them up, and maybe even blend in a blender or food processor to break up the sun-dried tomatoes and distribute them. That way you'll also be able to tell if you need more.
I hope that helps! If you try it let me know how it works! I'm curious to know. I love sun-dried tomatoes, and it would give other readers a good alternative.
Melissa says
How long if I'm using silicone trays in the dehydrator?
Willow Moon says
I've never used silicone trays, but from researching on Google it sounds like they take slightly longer than Teflon because Teflon transfers heat better. I would keep an eye on the crackers near the end of the drying time listed. It doesn't sound like it is going to make a drastic difference in the drying time. Let me know if you try it! I'm sure others might have the same question.
Karey A Spirit says
The nutrition information says "serving:24 crackers" does that mean each cracker is 92 calories? I hope not. Because there is no way that I would only eat one cracker at a sitting.
Willow Moon says
I know it’s hard to tell from the pictures, but I made the crackers large. So if you make them smaller they won’t be as many calories. A tablespoon of whole flaxseeds is 55 calories, so yes one cracker is 92 calories.
Cena says
Will these work if the flaxseed is ground?
Willow Moon says
Hi Cena, I haven't tried it with ground flax seeds, but that should work no problem. The ground flax will still get gelatinous once liquid is added and you'll be able to spread it.
